If you go into the UCP and head to the attachments list, the pagination in the top action bar says attachments but the one in the bottom action bar says Attachments with a capital A, the font size of the top pagination is also bigger than the bottom pagination.

This capital A is because in the ucp_attachments.html template, the top and bottom paginations have different language strings.

Top pagination:

            <div class="pagination">

                {NUM_ATTACHMENTS} 

Bottom pagination:

            <div class="pagination">

                {TOTAL_ATTACHMENTS} {L_TITLE} 

I think the top pagination string was supposed to be used in the bottom one too.

The bigger font size is caused by the top action bar having a 'top' class applied to it, the top action bars in other templates have a 'bar-top' class applied to them, 

This:

        <div class="action-bar top"> 

Should be:

        <div class="action-bar bar-top">
